Description

  The present invention relates to a handrail corner structure that forms a corner that is a corner or a corner of a handrail or a fence provided on a balcony or a roof.

  When handrails are attached to the veranda, rooftop or stairs of a building, it is common to fix a headboard member to the top of a column that is erected in a fence shape. As a head member, there are a member made of a single member formed into a cylindrical shape, a member made of a plurality of members including a substrate or a bottom plate and a cover, etc., which are appropriately selected and adopted. And when fixing such a head member to the top part of a support | pillar, it is common that the fixing member corresponding to a head member is fixed to a support | pillar, and it is comprised so that a head member may be fixed to this fixing member. is there.

  In the case of a handrail attached to the corner (corner part) that is a corner or corner that is configured on the veranda or the rooftop, a pillar is erected at the corner part, and fixing to fix the bilateral headboard member to this pillar A corner portion is configured by fixing a member and connecting a cap member extending from one direction and a cap member extending from the other direction at a predetermined angle via the fixing member (see, for example, Patent Document 1).

  On the other hand, for example, a structure in which a column is not erected at a corner is also known from the viewpoint of arranging the columns to be allocated to the outer wall forming the veranda parapet, from the viewpoint of reducing the number of members, and from the viewpoint of improving the design. For example, in the handrail corner described in Patent Document 2, corner metal fittings are arranged at the corners, and the two headboard members are connected to each other via the corner metal fittings so that the headwood members are suspended in the air. It is held in a floating state. The other end portion of the head member arranged in the two directions is fixed to the tops of a pair of struts arranged with the corners interposed therebetween, using screws or the like.

  In the technique described in Patent Document 1, a support column is erected at a corner portion, and a handrail is formed between the support column and an adjacent support column. Therefore, the headboard member has a both-end support structure and maintains a stable posture. can do. However, from the viewpoint of aligning the arrangement of the columns to the allocation of the outer wall, from the viewpoint of reducing the number of members, and from the viewpoint of design, the structure of Patent Document 1 in which the columns are erected at the corner is advantageous. I can't say that.

  In the technique described in Patent Document 2, since the support is not disposed at the corner, the above-described problem in Patent Document 1 can be avoided. Further, in this handrail corner, the headboard member arranged in the two directions of the corner is held in a state where the ends on one side are connected to each other and floated in the air, and the end on the other side sandwiches the corner. The head member is a cantilever support structure. For this reason, if the weight of the cantilever-shaped part is excessive, or if the distance between the column supporting the head member arranged in each direction and the corner is long, the corners are connected by the fixing member. There is a possibility that the end of the head member that forms the part hangs down and the appearance is deteriorated.

  In particular, when the end of the head member is attached to the top of the column with a screw or the like, the head member can easily start from the joint part with the column due to its own weight or the load acting on the free end side. Rotation, that is, the corner side hangs down.

  An object of the present invention is to provide a handrail corner structure that can suppress bending deformation of the head member caused by the weight of the head member at the corner without arranging a column in the corner. is there.

  In order to solve the above-described problems, the handrail corner structure according to the present invention includes an L-shaped corner accessory headboard that forms a corner that is a protruding corner or an inner corner, and a flat plate shape that covers the corner accessory headboard from below. And a pair of struts standing upright from the corners and supporting the plate member, and the plate member is passed above the struts at the top of the plate member A long reinforcing member connected to the plate member is provided, and the corner accessory headboard is connected to the plate member in a state of covering the end portion of the reinforcing member at a position spaced from the upper end portion of the support column. It is what.

  In the handrail corner structure, the tip portion of the corner accessory headboard extends to a position in front of the column as viewed from the corner and is connected to an intermediate headboard extending through the column. In addition, it is preferable that the corner combination headboard and the intermediate headboard are connected to the plate member in a state of covering the reinforcing member between the corner portion and the support column.

  Further, in the handrail corner structure, an end portion of the corner accessory headboard extends to a position passing through the upper side of the column as viewed from the corner, and extends in a direction away from the column. The corner accessory headboard and the intermediate headboard are connected to the plate member in a state of being covered with the reinforcing member at a position farther from the support column when viewed from the corner. preferable.

  In the handrail corner structure according to claim 1, the corner accessory headboard disposed at the corner is supported in the form of a cantilever beam by the support via the plate member and the reinforcing member, and is thereby supported by the support. A reaction force caused by the weight of the corner accessory headboard acts on the plate member. However, since the end of the corner accessory headboard is not supported by the support column, there is no risk of reaction force acting on the corner accessory headboard. Will be suppressed. In addition, the plate member on which the reaction force acts is also connected to the reinforcement member, and the reinforcement member also bears the reaction force, thereby suppressing the reaction force acting on the plate member, and bending and deformation of the plate member are also suppressed. Will be prevented.

  Further, in the handrail corner structure according to claim 2, the reaction force as described above is not applied to the corner accessory headboard, and the deformation of the corner accessory headboard caused by the reaction force is almost completely performed. Can be prevented.

  In the handrail corner structure according to the third aspect, the corner accessory headboard is constructed across the support column, and a reaction force acts on the corner accessory headboard. However, since it is laid across struts as described above, the moment acting on the position above the strut is smaller than the corner spear headboard with the end at the top end of the strut. The deformation of the headboard will be suppressed.

It is an expanded view explaining the handrail corner part structure which concerns on 1st Example. It is explanatory drawing of the principal part explaining the handrail corner structure which concerns on 1st Example. It is a figure explaining the relationship between a plate member, a reinforcement member, and a support | pillar. It is a figure which illustrates typically the handrail corner structure concerning a 2nd example.

  The handrail corner structure according to the present invention is configured without placing a support column at the corner of the protruding corner or the entering corner, and the bending deformation that occurs when the headboard that becomes the cantilever support structure hangs down on the free end side. Such a deformation can be suppressed.

  In the present invention, a corner accessory headboard configured in an L shape is disposed at the corner of the handrail. This corner accessory headboard has a connecting member arranged corresponding to the corner portion of the handrail, and is formed in an L shape by connecting the headboard member in two directions through this connecting member. .

There is no limitation on how the two-way plate members covering the lower part of the corner accessory headboard are connected at the free end, but it is supported by fixing the end on the support post to the support post. The Then, the corner accessory headboard is connected to the plate member supported by the support column.

  The reinforcing member is formed in a long shape, and is disposed in a state of passing over the support column, and is connected to a plate member supported by the support column. In other words, the reinforcing member is not connected to the column but only connected to the plate member. Further, the reinforcing member is not necessarily arranged in the center in the longitudinal direction corresponding to the upper end portion of the support column, but is disposed in an eccentric state corresponding to the positional relationship between the end portion of the corner accessory headboard and the support column. The length of the reinforcing member is related to the length of the corner accessory headboard, and has a length that sufficiently overlaps with the end when the corner accessory headboard is arranged corresponding to the corner. ing.

  Therefore, in the handrail corner structure of the present invention, the column is disposed at a position spaced from the corner, and the plate member disposed on the corner side on the column and the plate disposed on the opposite side to the corner side. Two plate members made of members are supported. And a reinforcement member is arrange | positioned so that the upper part of the two board members supported by the support | pillar may be straddled, and it connects with each board member. In addition, the corner accessory headboard is arranged so as to be opposed to the upper side of the plate member arranged on the corner side, and the end portion is located on the corner side from the support column or the end portion is beyond the support column and is opposite to the corner portion. It is located on the side and is connected to the plate member in this arrangement state.
